Banner Engineering's M18-4 self-contained photoelectric sensors are designed for harsh industrial environments where abrasive chemicals and ingress fluid are present. The 18mm metal barrel sensor features IP69K-rated 316 stainless steel housing and is built with application specific integrated circuit (ASIC) technology. This is designed to make the sensors resistant to fluorescent light as well as crosstalk avoidance. The M18-4 also featured a red emitter beam as well as a highly visible output, and dual-function power and stability indicators. The indicators are comprised of one green and two yellow LED lights. Solid green indicates power is applied and the sensor is ready, while green flashing specifies a marginal sensing signal. The two yellow LEDs, visible from both sides of the sensor, indicate the output is conducting. The M18-4 is available in opposed, polarized and non-polarized retroreflective, diffuse and fixed-field sensing modes and has an operating temperature range of -40 to 70 C.
